Throughout the headmaster’s address, and intermittently in all the lessons, he kept hearing his grandmother’s words and could only respond with last night’s prayer. More boys giggled each time he had to mutter. The teachers must be restraining themselves because of his grandmother — he had no idea how he might have responded if they’d spoken rather than merely frowning at him.

Tattered clouds like cobwebs laden with grime raced to meet him as he hurried home. They left the sky behind them no less dark. He let himself into the house and switched on the dimness before venturing upstairs. “You didn’t hear anything bad today, did you, grandma?” he whispered at her door. “God wouldn’t let you. Please God don’t.”

There was no sound from her room. If she’d been listening, the floorboards would surely have made her presence as apparent as they were making his. He was suddenly convinced he had been talking to nobody at all — for how long, he didn’t know. He grabbed the chilly scalloped brass knob and threw open the door.

The room looked yet more enormous for its emptiness. He could have imagined all the heavy mournful furniture was huddling against the walls. A wedge of murky twilight had managed to slip between the ponderous sombre curtains to emphasise the isolation of the bed, on which a fat faded patchwork quilt was drawn over a flattened stack of pillows. “Aren’t you there, grandma?” Jonathan barely said.

Perhaps he glimpsed the shadow of a cloud that was drifting unseen past the window, but the quilt appeared to stir as if something it concealed was trying to take shape and draw breath. He peered into the dimness until he grasped how terrified he was to see. Flinging himself backwards, he dragged the door shut and fled downstairs. “I’m sorry, grandma. I didn’t mean to-” he cried, and interrupted himself. “Please God don’t let her,” he repeated while he spread his schoolbooks across the kitchen table and attempted to work.
